Introduction: Carcinosarcoma, also known as malignant mixed Mullerian tumor (MMMT) is a malignant biphasic neoplasm consisting of carcinomatous and malignant non-epithelial components of mesenchymal origin. MMMTs typically arise from the female genital tract in patients over 40 years old. Primary extragenital MMMTs are extremely rare with published literature totaling 40 reported cases. The primary peritoneal carcinosarcoma is an aggressive tumor as patients with this tumor have an average survival of 7.6 months...

Purpose: To make clear distinction between two radiological types of uterine sarcomas. Methods: 50 preoperative MRI were analyzed retrospectively, blinded to histopathology: 11 endometrial stromal sarcomas (ESS), 19 leiomyosarcomas (LMS), 18 carcinosarcomas/malignant mixed Mullerian tumors (MMMT), and 2 smooth muscle tumors of uncertain malignant potential (STUMP). Results: According to their locations, two radiological types of sarcomas were identified: type 1: intracavitary (ESS, MMMT) and type 2: intramyometrial (LMS, STUMP)...

Carcinosarcoma (CS) is a rare, aggressive malignancy of the Mullerian system often termed mixed malignant Mullerian tumor (MMMT). It is biphasic in nature, differentiating into epithelial and sarcomatous components. Tumor-node-metastasis (TNM) staging and mismatch repair (MMR) status is the basis for both prognostication and therapeutic decision making. However, stromal differentiation (SD) is a new frontier in the field of histopathology and many studies have demonstrated its prognostic significance. The present study is the first study to evaluate the role of SD in carcinosarcoma...

This work aimed to design montmorillonite-incorporated pH-responsive and magnetic κ-carrageenan/chitosan hydrogels via a completely green route for controlled release of sunitinib anticancer drug. This was accomplished by ionic cross-linking of two biopolymers, κ-carrageenan and chitosan, in the presence of magnetic montmorillonite (mMMt) nanoplatelets. Interestingly, it was observed that the amount of mMMt affected not only the microstructure of hydrogels, but also the drug loading efficiency of nanocomposite hydrogels was noticeably increased by introducing mMMt (from 69 to 96%)...

Introduction . Ovarian carcinosarcoma (OCS), also known as malignant mixed Müllerian tumour (MMMT), is one of the rarest histological subtypes of ovarian cancer. It is an aggressive tumour with a dismal prognosis-the median survival of patients is less than two years. The rarity of the disease generates many controversies about histogenesis, prognostic factors and treatment of OCS. Histologically, OCS is composed of an epithelial and sarcomatous component. Case report . In the present case, a patient with bilateral ovarian cysts and bulky paraaortic lymph nodes is reported...

BACKGROUND: Gene therapy has held promises for treating specific genetic diseases. However, the key to clinical application depends on effective gene delivery. METHODS: Using a large animal model, we developed two pharmaceutical formulations for gene delivery in the pigs' vagina, which were made up of poly (β-amino ester) (PBAE)-plasmid polyplex nanoparticles (NPs) based two gel materials, modified montmorillonite (mMMT) and hectorite (HTT). FINDINGS: By conducting flow cytometry of the cervical cells, we found that PBAE-GFP-NPs-mMMT gel was more efficient than PBAE-GFP-NPs-HTT gel in delivering exogenous DNA intravaginally...

Carcinosarcoma (CS) or malignant mixed Müllerian tumor (MMMT), is a rare malignant biphasic tumor, which contains both a malignant epithelial and mesenchymal component. That being said, they have an aggressive clinical course. Given that immune checkpoint inhibitors have mustered significant excitement in the oncology world - immunotherapy could offer significant promise to this poor prognostic cancer subtype. A total of 75 carcinosarcoma cases were identified in our institutional database from 2010 to 2019 and immunohistochemistry for PD-L1, PD-1 and IDO-1 was performed...

BACKGROUND: Malignant mixed Mullerian tumors of endometrial (MMMT-E) and ovarian (MMMT-O) origin are associated with poor prognosis. Suggestively epithelial-driven tumors, their treatment has shifted from anthracycline or ifosfamide-based towards taxane-based chemotherapy. It remains unclear whether this change associates with better outcomes. PATIENTS AND METHODS: A conjoined Australian and Swiss patient cohort of MMMT-E (N = 103) and MMMT-O (N = 17) was compared to patients with adenocarcinoma of the endometrium (EC, N = 172) and ovary (OC, N = 189)...

Cervical carcinosarcomas (Malignant Mixed Mullerian Tumour [MMMT] ) are very rare neoplasms. Fewer than 100 cases were documented until recently. Because of the rarity, etiologic factors, prognosis and treatment modalities are unclear. A 53 year-old woman presented with postmenauposal vaginal bleeding and abnormal cervical cytology. Cervical biopsy followed by loop electrosurgical excision procedure (LEEP) and cold knife conisation (CKC) was documented as cervical intraepithelial neoplasia III (CIN III). Without follow-up, two years later, the patient was referred with a cervical 6,5 cm mass invading vagina, parametriums and rectum...

They include FIGO grade 3 endometrioid adenocarcinoma, uterine papillary serous carcinoma (UPSC), clear cell carcinoma, undifferentiated carcinoma and carcinosarcomas or malignant mixed Mullerian tumour (MMMT). The aim of this study is to look at clinicopathological features and survival outcomes of high-grade endometrial cancers of the uterus in our centre. A tertiary care centre in India. The study design is retrospective with survival analysis...

PURPOSE: Uterine neoplasms comprise a broad spectrum of lesions, some of which may pose a diagnostic challenge even to experienced pathologists. Recently, genome-wide DNA methylation-based classification of central nervous system tumors has been shown to increase diagnostic precision in clinical practice when combined with standard histopathology. In this study, we describe DNA methylation patterns of a diverse set of uterine neoplasms and test the applicability of array-based DNA methylation profiling...

BACKGROUND: Uterine sarcomas (US) constitute a rare heterogeneous group of gynecological malignancies with aggressive characteristics and poor prognosis. Identifying the histopathological factors that determine the prognosis of the tumor and efficacy of various treatment modalities provides a reliable source for efficient treatment of affected patients. This study presents our 11-year experience with US in the south of Iran. METHODS: Medical records of 42 patients (2001-2012) with endometrial stromal sarcoma (ESS), leiomyosarcoma (LMS), and malignant mixed Müllerian tumor (MMMT) were investigated...

Background: Intraoperative evaluation of an ovarian mass is of crucial importance in its further management, accomplished by frozen section (FS) and scrape smear (SS) examination. Aim: To evaluate utility of SS over FS and to study scrape cytological features of a variety of ovarian neoplasms. Materials and Methods: The study comprised ovarian tumors studied over a period of 1 year (2014-2015) that were submitted for intraoperative assessment...

Material and Methods: Patients diagnosed and treated for uterine sarcomas at our institution from 2009 to 2017 were retrospectively evaluated. All histological slides from the specimens underwent a thorough pathological review by a gynecological pathologist...

PURPOSE: To determine whether staging pelvic magnetic resonance imaging (MRI) can distinguish malignant mixed Müllerian tumor (MMMT) from EC. METHODS: Thirty-seven treatment-naïve patients with histologically proven uterine MMMT and 42 treatment-naïve patients with EC, treated at our institution, were included in our retrospective study. Staging pelvic MRI scans were reviewed for tumor size, prolapse through cervical os, and other features. Time-intensity curves for tumor and surrounding myometrium regions of interest were generated, and positive enhancement integral (PEI), maximum slope of increase (MSI), and signal enhancement ratio (SER) were measured...

Ovarian carcinosarcoma is also referred to as malignant mixed Mullerian tumor (MMMT). It is a rare neoplasm, and although it represents less than 5% of malignant ovarian tumors, it remains generally well-known among clinicians and pathologists. Rarer yet is ovarian teratoid carcinosarcoma, defined as carcinosarcoma with the added feature of immature neuroectodermal tissue, with or without elements of primitive germ cell tumor. To our knowledge, six ovarian teratoid carcinosarcomas have been reported in the literature [Matsuura et al...

Composite adsorption materials combine the advantages of various adsorptive materials and compensate for the defects of single adsorbents. Magnetic montmorillonite (MMMT) shows good adsorption properties for Pb(II). In order to further improve the adsorption properties of MMMT, in this work, Zn-BDC, a kind of metal⁻organic framework (MOF), was modified onto the surface of MMMT by in situ polymerization. The composite material MMMT@Zn-BDC was characterized by Zetasizer, SEM, TEM, FTIR, XRD, VSM, and XPS. The influence of adsorption conditions on the adsorption capacity of MMMT@Zn-BDC for Pb(II) was examined, including the adsorbent dosage, pH of Pb(II) solution, initial concentration of Pb(II), and the temperature and adsorption time...

Tamoxifen is used in the treatment of hormone-responsive breast cancer because of its antiestrogenic effect. However, it also has an estrogenic effect on the uterus, thereby increasing the risk of endometrial hyperplasia, endometrial polyp, and malignant mixed Mullerian tumor (MMMT). This case describes the pathogenesis and risk of MMMT due to long-term tamoxifen intake in hormone-responsive breast cancer.

RATIONALE: Malignant mixed Müllerian tumor (MMMT) of extragenital organs is rare, especially in male. To our knowledge, this is the first reported case of primary MMMT at the mediastinum in male. PATIENT CONCERNS: A 54-year-old male was admitted to the hospital due to repeated stimulating dry cough for 2 years. His systemic examination was unremarkable. Laboratory workup revealed that all blood indicators were within normal limits. But subsequent computerized tomography (CT) scans of chest showed an abnormal soft tissue density in the area of its left, measuring approximately 4 cm in anterior-posterior dimension and 7 cm in maximum transverse dimension...

Primary retroperitoneal carcinosarcoma or mixed malignant mullerian tumor (MMMT) is an extremely rare clinical entity. These aggressive tumors arise most commonly from genital tract. The retroperitoneal location is exceptional. Here we report the case of a 63-years old female diagnosed with heterologous, extra-genital, retroperitoneal carcinosarcoma, with malignant cells in the ascitic fluid and extra-ovarian metastatic implants. She was treated with complete radical surgical treatment consisting of resection of the retroperitoneal tumor, with omentectomy, hysterectomy, bilateral salpingooophorectomy and lumbo-aortic and pelvic lymphadenectomy...
